Flying less or more generally consuming less is not going to solve the climate crisis. We need to go to net zero emissions and then to net negative emission, we need to capture the excess of GHGs to go back to a level where warming stops.<p>If we divide, let's say, by 10 the emissions, we are still emitting too much.<p>The only solution is too eliminate completely the use of fossil fuels. For flying this means zero emissions planes (electric, hydrogen, ...) and/or synthetic fuels.<p>Synthetic fuels is probably the fastest path to net zero emissions: no need of new technology, no need even to build new airplanes.<p>Synthetic fuels is quite easy, if electricity is cheap enough synthetic kerosene will be cheaper than classic kerosene. Luckily, thanks to renewables, electricity is becoming exponentially cheaper.<p>Several companies are on the path of producing synthetic fuels cheaper than fossil ones. One example in mind: terraform industries in Pasadena.
